IMPROVEMENT IN CHIMNEYS.

The Schedule referred to in these Letters Patent and making part of theBanm To all whom it may concern.-

Be it known that I, BENJAMIN F; MANN, of Oakland, county of.Alameda,State of California, have invented an Improved Earthquake-Proof Chimney;and I do hereby declare the following description and accompanyingdrawings are sufficient to eu'ablel any k person skilled in the art orscience to which it most nearly-appertains, to make and use my saidinvention or improvement, without further invention or experiment.

My invention relates to a new ,and improved chimney for houses, soconstructed ythat it cannot be af'- fected by shocks of earthquake orhigh winds. It also presents other advantageous features, which will behereafter recited, which renders it far preferable to any other form orconstruction of chimney now used. In California especially, where theground is frequently shaken by earthquakes, it has been ,found necessaryto provide a more staid and substantial chimney for buildings in orderto prevent their being toppled or injured by the shocks.

Thisl'propose'to do by constructingr the chimney entirely of metal, insuch a manner that it 'will be firmly secured from moving from anycause.

This chimney can also be constructed quicker 4and cheaper than theordinary chimneys in use.

To more fully illustrate and explain my invention, reference is had totheaccompanying drawings, forming a part of this specification, ofWhich.-

Figure 1 is av front view, showing a section of the chimneys.

Figure 2 is a side` sectionalvview, showing the diaphragms for theiiues.

Figure 3 is a top- View.

Similar letters of reference, in each of t-he figures, indicate likeparts. Y

A. is the lower portion oi' the chimney, which may extend to the floorof the second story, or above, as found desirable.- 4 p This portionofthe chimney is made of any suitable shape,\and is intended to restupon any proper foundation or upon theA fioor, if desired, as the entireweight ofthe chimney when built will not exceed six or seven hundredpounds.

This portion of the chimney is made of cast, sheet,'

or boiler-iron, riveted together, and the properopening,.B, is left fora lire-place, which may be built of brick.

It' a chimney with a single `fire-place and flue is re' quired, the topshown at iig. 2 is employed.

This top is cylindrical in shape, and consists of two cylinders orpipes, c b, the one 'inside of the Iother 'having an annular spacebetween them, which I iill with cement,plaster of Paris, asbestos,

conductor of-heat.

This top is secured to the cover D, Whichis placed or other nonover thetop of the section A of the chimney, and held by rivets or other means,an opening being left-in the cover D, over which the top is placed, toallow the smoke to pass up the chimney. p

. When the chimney is intended for two dre-places, two ues, E and F,shown at fig. 1, are employed, one placed at each end ofthe cover D',and constructed similar to the one Vabove described. v 'In order toseparate the main or lower section oi` the chimney, so that the smokefrom each fire-place will ascend-through the proper fl,ue,I take-a sheetci' metal, G, to the upper side of which I attach another metal plate,g, at right angles to the plate G. This plate g is then bent down inopposite corners, so as to leave the dues It h diagonally opposite toeach other, as shown at iig. 3.

A small metal plate, is attached -and hegt, so as to stand across thechimney above the plate g, and at right angles to it.

The plate G, with its attachment-s, is then placed inside the section A,from the top, and droppeddown until it rests upon suitable stops, n a,on each ls'ide ot' Y the section A, bringing the top of the verticalplate fi A even with the top of the lower section; thus,"when the coverDis secured over the'top oi' the section A, forming two openings, one oueach side, leading into the upper chimneys or iiues.

The two lire-places are intended to open into adjoining rooms onopposite sides oi' the chimney, and the 'plate Gr will meet, and mayrest vupon theircommon back, or the division between them, built ofbrick or other suitable material, as shown at J, iig. 2.

rlhis chimney, as before stated, may be-placed di.

rectly upon ythe oor ofthe building, and any suitable fire-prooffire-place be constructed in-the recess left in the section A.

The boards or wood-work may be arranged so 'as to t close up against thechimneys, and there will be no danger of its taking fire, as the fillingin the annular space will keep the outside always cool, and by thusbringing the wood-work close. up vagainst it, the chimney will be stayedto its place'.V

Heating-drums may be connected with the chimney u at any point, and thusutilize the heat that would otherwise be wasted, in warmingadjaceutrooms.

Two rooms on the same floor can easily be warmed by one re, as the heatin the re-placeonone side will be suiiicient to penetrate the backwall,andthus givea pleasantdegree o f warmth to the room next'A adjoining.

The lightness of this chimney renders it quite applicable when are-place is desirable only in the up per story or stories of a building.It may also become an article of manufactureand kept on hand by dealers,thereby facilitating they rapid construction of houses.

`The exposed portion of the iron, both insideth'e house and above it,can be painted in imitation of brick-work, or a frame may surround thechimney above the roof, and will thus present a similar appearance to a.brick chim'ney. y i

Having thus described my invention,

What I claim, and desire to secure by LettersPatent, is-

The combination, with two or more metallic chimney-iues, E and F, of abase section, A, provided with a removable partition, consisting of thevertical plate G, the horizontal plate g, having openings h, and thecross-plate z', the same being constructed and arranged'snblstantiallya's herein described.

In witness whereof, I have hereunto set my hand and seal. i
